High-temperature gloves |
| 1Double | Excellent comfort and keeps hands warm; cut-resistant, wear-resistant, and heat-resistant (can withstand 350℃ for 60 seconds of contact heat, 100℃ for 180 seconds of contact heat) durable. | |
Heating Element | Silicon carbide rod |
| 2Please provide the Chinese content you would like translated into American English. | Silicon carbide components, with high operating temperatures, are hard and brittle. After shaping, they are used, such as silicon carbide rods and tubes, which can reach high heating temperatures under air-dry conditions.1500100-120°C, for use under vacuum conditions; 1000-1200°C under nitrogen atmosphere; long-term use temperature 1350°C |
Silicon Molybdenum Rods |
| 2Branch | Silicon molybdenum rods are heated to high temperatures under an oxidizing atmosphere, where a dense quartz glass film forms on the surface to protect against further oxidation. Therefore, silicon molybdenum rods exhibit high-temperature oxidation resistance. Under oxidizing conditions, temperatures can reach1800℃, can be used as a heating element for high-temperature furnaces in industries such as electronics, ceramics, magnetic materials, glass, metallurgy, and refractory materials. | |
Pot tongs |
| 1Please provide the Chinese content to be translated. | A common chemical instrument, typically used for holding crucibles. Generally made of stainless steel or hard, non-combustible, and non-oxidizable materials. 2. Use clean tongs. 3. When handling a hot crucible with tongs, preheat the tips to prevent the crucible from cracking due to localized cooling. After use, place the tongs with the tips facing up on the table or a asbestos mat. 4. After the experiment, the crucible tongs should be cleaned, placed in the equipment cabinet, and allowed to air dry. 5. Use the bent section for holding crucibles; use the pointed end for other applications. 6. Crucible tongs are not necessarily used in conjunction with crucibles; they can also be used independently. | |

Special Note
Quality Warranty | One-year full machine warranty, excluding related consumables (mold boards and heating elements excluded)Lifetime On-Site Maintenance |
Factory environment | 1. Indoor Use 2. Environmental temperature is within ±5-45°C range. 3. The relative humidity of the surrounding environment should not exceed 85%. 4. No conductive dust, explosive gases, or gases that can severely damage metals and cause insulation corrosion are present around the stove. |
Safety Protection | 1. When first using or after a long period of non-use, an electric furnace must be baked to prevent cracking of the furnace chamber. Keep clean regularly and check if the electric furnace wiring is in good contact. 3. Do not exceed the rated temperature when using the furnace to prevent damaging the heating elements. Prohibit pouring various flammable liquids and melted metals into the furnace. 4. During the process, the temperature should generally not exceed 300℃ and the rate of temperature increase should be moderate. This is because, when heating begins, the furnace is cold and requires a significant amount of heat to be absorbed. |
After-sales service | 1. We promise to address our customers' technical queries within 1 hour. 2. We promise to provide a test result within 1 working day for equipment returned for repair, complete the repair within 3 working days, and handle special materials on a case-by-case basis. 3. Within one week of returning the equipment to the customer, conduct a follow-up visit with the user and provide free technical consultation. |
Friendly Reminder | Do not operate the equipment at the rated temperature for extended periods to ensure its normal service life. 2. Carefully count and verify the quantity of goods and accessories upon receipt to avoid any inconvenience caused by shortages or omissions. 3. To extend the lifespan of the instrument, we recommend that the heating and cooling rates do not exceed 10℃/min. 4. The cooling rate should not exceed 5°C/min. 5. This furnace does not have a vacuum-sealed structure, therefore it is not suitable for introducing flammable or explosive gases. 6. After some time of use, the furnace chamber may develop minor cracks, which is a normal occurrence and will not affect operation. These can be repaired with an alumina coating. |
